“…These advantages include higher combining efficiencies due to reduced insertion loss and improved amplitude and phase balance, as well as reduced physical size and weight [1]- [3]. With few exceptions, these types of combiners have traditionally been difficult to design: Electromagnetic field analysis is used in [4], empirical techniques based on measurements is used in [5], and for some others no detailed design information is provided [6]- [8]. With the advent and continued improvement of 3D electromagnetic modeling software, the analyses and simplified design approaches of many variations based on radial, coaxial and conical transmission lines have been presented [9]- [15].…”

Abstract-A simple equivalent circuit model with empirical equations describing the peripheral feeding ports of conical line power combiners is presented. The model allows the entire structure to be designed using transverse electromagnetic circuit theory without the need for any full-wave simulations. A summary of the model extraction process is given and the accuracy of the proposed model is confirmed by favorable comparisons with full-wave simulations. The circuit based design method is used to design a compact conical line combiner showing measured performance similar to the current state of the art combiners in this technology, while being significantly smaller.
